Re: Any advice how to optimize OpenGL on hawaii architecture?

Hi,

http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/opencl-optimization-guid…

Also you can learn a lot from: http://developer.amd.com/wordpress/media/2013/07/AMD_Sea_Islands_Instruction_Set_Architecture.pdf

Some easy hints:

- Don't use more than  128 vector registers.

- Schedule at least 4x more workitems than the number of streams in the device.

- use 24bit integer math if it is possible

- ensure that the kernel code is not larger than 32KB (for the main loop.)
